Marlborough: Reading the Three Valleys

FIELD NOTE 01

Wairau Valley

This is a wide area with riverbed gravel soils. Conditions are different inland, in stony, early-ripening locations, and along the coast exposed to sea breezes. It's important not to fix one temperature or harvest time by the name Wairau alone.

FIELD NOTE 02

Awatele and Southern Valleys

South Awatere is relatively cool, dry, and windy. In Southern Valleys, compared to Wairau, there are areas with more clay, making Pinot Noir important as well. In both cases, describing the region by Sauvignon alone is insufficient.

FIELD NOTE 03

Leading up to winemaking

Besides styles designed to retain aroma, there are whites with texture shaped by barrel fermentation or lees contact. With Chardonnay, Pinot Noir, and traditional-method sparkling, you see that one region produces multiple wine styles.

FIELD NOTE 04

Divide into Wairau, Southern Valleys, and Awatere.

If you think of Marlborough as a single flat vineyard, you'll overlook the differences between valleys. On the map, set Wairau Valley as the baseline, then add the Southern Valleys including the hills to the south, and Awatere Valley even further south. Official regional explanations note the tendency for clay soils in the Southern Valleys and describe the landscape of Awatere stretching inland from the sea.

While the micro-region name can help narrow down vineyard conditions, not all grape varieties grown there will have identical ripeness or aromas. Even for Sauvignon Blanc, it's necessary to examine harvest decisions and subsequent fermentation.

FIELD NOTE 05

Read Te Koko 2023 as a step beyond the region’s typical expression.

Cloudy Bay notes that Te Koko’s grapes come from selected parcels in Wairau. The 2023 information mentions controlled yields, monitored ripeness and acid, hand harvesting, wild yeast fermentation, and aging on lees in barriques, large oak vessels, and concrete vessels.

Within the common ground of 'Sauvignon Blanc from Marlborough,' there are distinctions in fruit selection and vessel use. Don’t equate 'barrel fermented' with '100% new barrels,' and do not fill in unlisted percentages or durations—this is foundational to reading product specs accurately.

FIELD NOTE 06

Taste the differences between regions and winemaking methods separately

For the first comparison, select two bottles from the same year and grape variety but from different subregions. For the next comparison, choose different winemaking styles from the same producer. The former offers an entry point to consider vineyard differences, the latter for winemaking techniques, but neither is a fully controlled experiment. Rather than adopting the producer's flavor description as your own conclusion, it is easier to structure your explanation by recording your impressions in four categories: fruit, acidity, texture, and barrel aromas.
